I have a Wii that will not accept any discs. It is not modded, it is a US Wii with 3.1u firm on it. The laser lights up when powered on and then nothing. Any ideas as to what could cause it? The system works fine aside from the disc drive, goes to menu and all that good stuff just the drive seems to be lacking power or is shorting out. I am pretty good with fixing things just do not know where to start on this one. Any help would be appreciated.
